It's true. Maybe I'm wrong about this but it seems to me that at some point most pages "settle". I'm also planning to put in a hard timeout in what I'm building. And I'm slightly more concerned about js than css.
Do you know of a good way at getting at an event queue or something else containing a list or a count of upcoming setTimeout/setInterval operations, in either Safari or QtWebKit?
